Zima

Zima is a "clearmalt beverage" produced by Coors sice 1992. It is
essentially beer that has been filtered through charcoal to remove
color and flavor, then injected with flavorings that make it taste
something like a flat, metallic gin and tonic. Zima Gold, launced in
1995, is produced the same way and taste something like a flat,
metallic rum and Coke.
